Number of times DB2 detected that a RID list exceeded one or more internal limits during a given RID list (or RID pool) process involving one index (single index access with list prefetch), or involving multiple indexes (multiple index access).
The internal limits include the physical limitation of the number of RIDs a RID list can hold and threshold values for the retrieval, ORing and ANDing of RIDs. For index access with list prefetch (single index), this field can only be incremented during RID list retrieval. For multiple index access, this field can be incremented during RID list retrieval, RID list anding and RID list oring. This counter reflects the number of times internal limits or threshold values were exceeded for the RID lists obtained directly from an index as well as for RID lists derived during the ANDing and ORing process.
